Japan's claim is a longstanding source of its diplomatic tension with South Korea, along with the its assertion that all matters related to apologies and reparations for its brutal 1910-45 colonization of Korea were settled in a 1965 state-to-state deal and some subsequent statements.

   It is the sixth consecutive year Japan's foreign minister has laid claim to Dokdo in the annual address.

   On historical issues, Kono called on Seoul to abide by relevant "international promises."

   Last year, South Korea's Supreme Court upheld rulings in favor of Koreans who served as slave workers at Japanese factories during World War II.

   The Moon Jae-in administration has also pushed for a "victims-oriented" approach in handling the issue of Korean women forced to serve as sex slaves for Japanese troops during the war. (Yonhap)
